Supplying the board from E5V (CN3 or CN12)
Figure 10. CN8 (External 5V supply)
From E5V: 5V DC power adapter connected to CN3
In this case, the STM32F7308-DK board must be powered by a power supply unit or by an
auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009 connected to
CN3, and must be Safety Extra Low Voltage (SELV) with limited power capability (5 V power
source on silkscreen “E5V” see
From E5V: 7-12V DC power from CN12 (VIN)
7-12 V DC power supply is provided by an Arduino Uno V3 compatible shield connected to
CN11, CN12, CN13 and CN15 connectors.
This 7-12 V voltage (VIN) is then converted to 5 V by a LDO (U11).
Finally, the user must fit the jumper on "E5V" position on CN8 connector, to select this LDO
output (E5V) as main power supply for the board (see
).
7.4.4
Supplying the board from an external power supply through USB HS
A 5 V DC external power supply is connected to USB OTG HS Micro-AB connector CN19
(5 V power source on silkscreen “USB_HS”, refer to
